Migrant integration in Arnsberg has primarily taken place by opening up the core institutions, such as the education system and the labour market, to migrants and by including migrants in the national welfare system. With regard to the housing market, this means that non-Germans have the same legal rights as Germans to apply for housing assistance. The most important measures for low income households have been the availability of council flats and the housing allowance. Socio-spatially, foreigners have been well integrated into city life. However, some segregated housing areas do exist, and numerous concepts, measures and initiatives have been introduced to combat this problem.
